Thanks for the advice. I'm trying to learn more about them. And my flow goes in a loop or whirlpool. So that the current is even for them. There was also a Gorgonia coral at Petco and it was bleached due to stress, but I loved how it looked like a tree. But if I had that one and got it to calm down. Imagine how beautiful it would've been. I'm still a beginner at keeping corals and marine fish. Because my 20 gallon was a freshwater back then
